Another question occured to me, and this is probably a simple one for those with more experience. I use calculated shipping, connecting to both USPS and UPS. I've never been able to figure out which shipping method to select in the feed configuration to get this to work correctly. Some options cause it to show up as free shipping, some as no shipping.

I can use the shipping options directly in Google, but they don't offer First Class and many of the items I sell are lightweight. This makes the items show in the results with a total cost that is much higher than reality.

Does anybody know how to set this up correctly in the feed?
